Add JavaScript for validating diff files.
Review Request #4320 — Created July 11, 2013 and submitted
Add JavaScript for validating diff files. This is the client side of the diff validation resource. To use this, one instantiates the model, sets the repository/diff/parent diff/basedir, and calls save(). Either the "success" or "error" callbacks in the options object passed to save will be called, based on whether the diff parses correctly and the source files exist.
- Ran unit tests. - Used this with a number of different diffs that caused various errors.
